SetIterator.toString Method [AX 2012]
Returns a textual representation of the current element in the set that is pointed to by the iterator.
If the iterator points to the first element in the set, the string will contain an indication of this, in the following format: "(begin)[value]" If the iterator does not point to an element (that is, if more() returns false), the string returned is: "(end)" If the iterator points to a value the string is: "[value]" where value is a string representation of the element value.
The following example uses the SetIterator.toString method to print a description of the value in the set that the iterator points to before it starts traversing the set.
{
Set s1 = new Set (Types::Integer);
int theElement;
SetIterator it;
// Add some elements
s1.add(3);
s1.add(4);
s1.add(13);
s1.add(1);
// Start a traversal of the elements in the set
it = new SetIterator(s1);
// The elements are fetched in the order: 1, 3, 4, 13
print it.toString(); // Prints "(begin)[1]"
while (it.more())
{
theElement = it.value();
print theElement;
// Fetch the next element
it.next();
}
pause;
}
